Would have done that, but tested 2 such boards out. Both have the same problem, which seems highly inconvenient

Hi

PFA the link to the user manual for the board

https://warp9td.com/images/BOB_Vendors/StepperOnline/ST-V2.pdf

@TPS Yeah we did try that. the same problem for pins 10, 11, 12 but 13 and 15 work fine

General Mach Discussion / Mach3 Breakout Board Inputs
« on: February 07, 2019, 08:15:28 AM »
I have a Mach3 PCI breakout board. Am trying to configure my limit switches to 3 of the 5 input pins available(10,11,12,13,15).
So my configuration is as follows:
X Axis Limit switch: port 1 pin 15
Y Axis Limit switch: port 1 pin 13
Z Axis Limit switch: port 1 pin 12

The x and y axis limit switches do trigger the interrupt on the software but the z axis does not. Have verified that the limit switch works fine. In fact when I put the z axis signal into the x axis pin, it does trigger the interrupt. I feel that there is some error in the port and pin configuration for the z axis. Any help in this regard is much appreciated.

Thank You

Hi,
We simply kept reducing the acc and velocity till we got smooth movement by the motor. Even though it works right now, I am not convinced with this solution. If there is anything else that can be done, pls let me know.

To answer previous suggestions, we did swap motors and drivers, but the problem's only there on the X-axis

We tried that, brought it down to its lower limit, which is practically not feasible. Though as we kept going down the frequency of those stops occurring decreased, they were not completely gone.

Thanks, will try that and get back to you

We did that, but did not feel any additional torque requirement needed to rotate the ballscrew at any point

I have a 3 axis CNC.

There is a problem running only the X-axis motor. It sometimes misses rotation and in that miss there is a noise coming from within the motor which sounds like gears grinding against each other. At other times it just completely stops while running, with the same background noise coming from the motor.

Peculiarly it happens at only 2 spots along the X-axis. Y and Z axis run fine. Redid my wiring as earlier it was messy and I thought that some noise might be interfering with the signal wires going to the motor driver, but that did not help.

Any help is much appreciated.

Thank You

Can you please tell me why do we not get meaningful readings when using continuous mode on a powered up circuit?
